Collaborative Virtual Prototyping and Test

Abstract

This paper discusses a cost‐effective system for virtual collaborative simulation of prototypes, tests, and production for integrated product/process development. The virtual prototypes perform three‐dimensional modeling of the physical operation of equipment and weapon systems. Realistic qualification tests are modeled to allow assessment via simulation without building hardware. The risk of transition to full production manufacturing is mitigated by virtual testing integrated with production simulation. A virtual collaborative interface is utilized to allow the simulations to be distributed and exchanged over a network (including the Internet). The feasibility of the collaborative virtual prototype and test environment has been shown with simulations hosted on a server and accessed by desktop computers over the Internet.

Modeling Method and Application in Digital Mockup System towards Mechanical Product

“…Ed P. Andert considered DMU as a virtual manufacture and simulation process from the point of view of mechanical engineering. The design model based on DMU stores all the information about mechanism, physics, appearance and functionality of actual mockup [7]. Mitchell M. Tseng indicated that DMU is a digital model which is able to substitute for real product model and check the geometry, function and manufacturability [8].…”
